Predictive model of decontamination efficiency of gaseous pollutant by non-equilibrium plasma

During non-equilibrium plasma (NEP) reactions, chemical bonds of pollutant compound are broken by energy generated in the reactor so that the pollutants are decontaminated. In this study, the energy conversion factor (Ef) is defined as the ratio of the dissociation energy of chemical bonds destroyed in NEP reaction system to the energy inputted in plasma reactor. The energy conversion factor of chemical bonds (Ef,i), S–H, C–Cl, C–S, C–H, C–C etc., were determined by decontamination experiments of H2S and 2-CEES in plasma reactor. Based on the Ef,is, the predictive model of NEP decontamination efficiency of gaseous pollutant was developed and applied to predict decontamination efficiency of CH3CH2SH, in which all Ef,is of chemical bonds are known as described above. It was shown by the decontamination experiment of CH3CH2SH that the predictive value was well agreed to experimental data. Therefore, the model can be used to predict decontamination efficiency of those pollutants in which all Ef,is of chemical bonds have been determined. An improved model is also produced by the analysis of predictive error.
